tion will become apparent from the following detailed description takenin connection with the accompanying drawing which show the invention inits present preferred form and in which:

Fig. l is a side view of the clip and its contained cartridges as acomplete packet;

Fig. 2 is a vertical section of the packet along line D-D of Fig. 1;

Fig. 3 is a rear View of the empty clip;

Fig. 4 is a front view of the empty clip;

Fig. 5 is a top view of the empty clip;

Figs. 6, 7 and 8 are horizontal sections of the empty clip takenrespectively along the lines AA, BB and C-C of Fig. 1.

Referring more particularly to the drawing, the clip as a whole isindicated by the numeral I and the cartridges as 2. These cartridges areof the usual form, slightly tapered as shown and having grooved bases(not shown) for extraction after firing.

The clip is designed to hold the cartridges in a double row stack withone row higher than the other, the cartridges being in staggeredrelation, those of each row resting one upon the other and mutuallyengaging the cartridges of the other row, as clearly shown in Fig. 2.When the clip is full and ready to be charged into the gun magazine, thestack of cartridges will be tightly held in the compact form shown by aspring clamping action of the clip. The clip comprises a back 3 V andtwo sides 4 and 5 which may be conveniently formed from a one piecestamping of spring metal. The sides 4 and 5 preferably converge in aforward direction toward one another and are,

spring tempered to firmly clamp the contained stack of cartridges andimpart ala'tertal pressure thereon. The back 3 and the sides 4 and 5being preferably of thin metal are suitably stiffened by the upset ribs6, I, 8 and 9 and cut-out openings are made therein for lightness.

The sides 4 and 5 are each formed at their upper ends with inturnedportions I and II, preferably symmetrical and at the same eleva tion toact alternately as the upper rest for the higher row of the stack as thesame is fed upwardly in the clip by a feeding follower of the gun (notshown). A latching shoulder 29 is provided on the back of the clipadapted for engagement byalatch of the gun (not shown) for retaining theclip in the magazine.

It will be understood that in the operation of a gun with a clip of thischaracter, the bolt or breech closure during its forward movement will10' pick off the topmost cartridge alternately from 7 each row forloading and that a suitable follower of the gun engaging the bottom ofthe stack will raise the stack in the clip after the removal of eachcartridge from the top thereof. It is not deemed necessary to show suchmechanism of the gun but for an example of such a construction referenceis made to'my co-pending application Serial No. 197,718, filed'June 9,1927.

The sides 4 and 5 of the clip are each formed at their lower ends withspring acting inturned portions I2, I4 on one side and I3, I5 on theother side. The portions I2, I4 are positioned some-.

what lowertha'n portions I3, I5 and'said respec- H tive side portionsprovide the bottom rest for the lower and upper rows of the stack. Thenarrow tongue-like portions I4 and I5 particularly are designed toimparta vertical pressure on a full stack contained in the clip, wherebyin conjunction with the lateral clamping pressure previously described'afirmly held packet is obtained. At the rear of each side 4 and 5 andadjacent the back areformed inwardly projecting ribs ZI and 22which'extend'verticaily (as shown in Fig. 1) from a point near thebottom of the clip to a point slightly more spaced from the top. These vribs ZILand 22 are adapted to engage in the grooves, i. e., in front ofthe extracting shoulders at the bases of the cartridges (not shown), andhelpto retain the cartridges in the clip and pre vent their falling orshaking. out when carried as .a packet. Preferably the-ribs 2I, 22extendhigh enough to just miss engaging the extracting groove of the .topcartridge of 'an upper row, 7 7

and I1 is made by upsetting the metal outwardly slightly to formshoulders l8 and I9, one for each clip side 4 and 5, respectively. Thefunction of the shoulder l8 will be described and it will be understoodthat shoulder l9 acts in a similar manner when its adjacent row ofcartridges is the lower one.

It will be observed in Fig. 2 that the upper row of cartridges isengaged both at the top and bottom by the inturned. portions H, and l3,l5. The lower row on the other hand is engaged at the bottom by theinturned portions l2 and 14,. but is spaced from the upper clip portionHi. The stop shoulder I8 is therefore provided to engage the topcartridge of the lower row to prevent possible dislocation of this topcartridge due tothe upward pressure from'beneath the stack. which isoccasioned when the stack is full (and either in or out of the magazine)by thespring portions l2, l4 and l3, l5, and when the stack is being fedupwardly by theworking. pressure of the follower (not shown) The stopshoulder l8 furnishes a sufficient check against any tendency of itsengaged top cartridge to tip upwardly under the pressure described andyet will permit said top cartridge to easily ride past the same intoengagement with the upper inturned portion l0 after the top cartridge ofthe higher row has been picked. off in loading. The shoulders l8 and [9,therefore, act alternately as a check stop for the top cartridge. of thelower rowiof the stack during the. feeding operation of the fol-- lower.In use, it is found that the lateral pressure of the clip sides willthrow the top cartridge. of the higher row very slightly to the left andcause. the top cartridge of the lower row to. seat partially in therecess [6, behind the shoulder i8, and thus provide the effective stopdesired.

Various modifications of the structure as shown are obviously possiblewithout departing from. the spirit of the invention. as hereinafterclaimed- Lclaim:
